AccuSilver is a corrosion resistant silver plating that has an aesthetically pleasing appearance. It is commonly used within printed circuit boards and electrical connections due to its superior electrical conductivity. It is used in the medical industry because the silver ions prevent bacterial build-up by absorbing oxygen, which kills microbes, but is harmless to the human body. The AccuSilver coating can be applied to any stainless steel components upon request. Accu stocks A2 stainless steel Flat Washers with the Accu Silver coating, which are available in nominal sizes M2 to M12 with varying thicknesses. These washers are often used with our Precision Screws to enhance the load-bearing capabilities.
